its the egr valve. a tricky little piece to get to under the bonnet and the part costs over £200. we are currently on our 4th in the last 4 months! its a bad bit of engineering and a friend iof ours is going to block it all off becuase at this rate its going to be one a month. the big give away is the horrible acrid smell from the exhaust plus loads of white smoke and the fact that there is absolutely no power in the aceleorator, its gets worse as the car gets choked up and eventually cuts out completely. very dangerous if it does this going up the A14!
sorry to be bearer of bad news.
